Brown the ground beef with the onion and garlic in a skillet over medium heat until ground beef is fully cooked, crumbled, and no longer pink. Drain and discard any fat. Place the skillet back on the heat and add in the bell peppers, diced tomatoes, rice, beef broth, tomato paste, Italian seasoning, salt and pepper. Stir to combine and bring mixture to a boil.
Reduce heat to a simmer, cover and let cook for about 18 minutes, until rice is cooked through.
Fluff the rice with a fork and top with the shredded cheese. Cover again and let cheese melt over low heat. Garnish with fresh parsley and enjoy!
